Hello,

I am using watem-sedem version 5.0.2

I read the Github documentation on how to set up the model and did the tutorial which worked fine. My question is.... How do I format the raster so theres no data values in it? On their page they have "Note

WaTEM/SEDEM does not take nodata values (e.g. -9999) into account. When a nodata value in the DTM raster is encountered, it is considered as an elevation value. Consequently, slopes will be calculated wrongly. Thus, the user must ensure that all pixels in the model domain have an elevation value, and that at least two pixels outside the model domain have a valid elevation value."

I am using ArcGIS Pro, Python, and QGIS for spatial mapping and manipulation. I have a raster shaped like a watershed and there's no data values surrounding it, which is expected. thanks!
